EXAMPLE
students in class should focus on what the teachers are saying and the
overheads being presented. Students walking by the classroom may focus on people in the room, who is the teacher,
etc., and not the same thing the students in the class.

the world is a function
of our past experiences,
culture, and biological makeup.
EXPECTANCY
EXAMPLE
You may look at a painting and not really understand the message the artist is trying to convey. But, if someone tells you about it, you
might begin to see things in the painting that you were unable to see before.
* It has been widely interpreted as representing the universal anxiety of modern man.* I was walking down the road with two friends when the sun set; suddenly, the sky turned as red as blood. I stopped and leaned against the fence, feeling unspeakably tired. Tongues of fire and blood stretched over the bluish black fjord. My friends went on walking, while I lagged behind, shivering with fear. Then I heard the enormous, infinite scream of nature.
ALL OF THESE…are called
Psychophysics(the relationship between
physical stimuli and the sensations and perceptions they affect.)
